Corrosion is a natural process, which converts refined metal to their more stable oxide. It is the gradual destruction of materials (usually metals) by chemical reaction with their environment.In the most common use of the word, this means electrochemical oxidation of metal in reaction with an oxidant such as oxygen.icrobial corrosion, or commonly known as microbiologically influenced corrosion (MIC), is a corrosion caused or promoted by microorganisms, usually chemoautotrophs. It can apply to both metallic and non-metallic materials, in the presence or absence of oxygen.
Graphitic corrosion is selective leaching of iron from gray cast iron, where iron particles are removed and graphite grains remain intact. Graphitic corrosion is also known as selective leaching, dealloying, demetalification, parting and selective corrosion.
